Summary
Fixed-interval spaced retrieval (FISR) and randomized-interval spaced retrieval (RISR) both effectively treat anomia in persons with aphasia (PWA). While FISR required fewer sessions, RISR
Area of Science:
- Neurolinguistics and Speech-Language Pathology
- Cognitive Rehabilitation
Background:
- Spaced retrieval (SR) is a memory-based learning technique adapted for treating anomia in persons with aphasia (PWA).
- Traditional SR utilizes a strict inter-stimulus interval (ISI) management, adjusting presentation times based on response accuracy.
Purpose of the Study:
- To compare the efficacy of fixed-interval spaced retrieval (FISR) versus randomized-interval spaced retrieval (RISR) for anomia treatment.
- To determine if the strict ISI management in SR is essential for successful anomia rehabilitation.
Main Methods:
- Employed an alternating treatments single-subject design.
- Three PWA participated in the study, trained on naming 30 target items using either FISR or RISR.
- Intervention effectiveness was assessed through response accuracy and item maintenance on post-treatment probes.
Main Results:
- Both FISR and RISR demonstrated success in treating anomia.
- FISR required fewer treatment sessions and showed slightly better item maintenance.
- The observed differences between FISR and RISR were minimal, suggesting comparable treatment outcomes.
Conclusions:
- A less stringent stimulus schedule, such as RISR, is sufficient for effective anomia treatment.
- The strict ISI management in traditional SR may not be a necessary component for successful outcomes.
- Both fixed and randomized interval approaches offer viable options for anomia rehabilitation in PWA.
